20WILL SMITH (SUPERMAN)
Michael B. Jordan as Superman might be the hottest casting rumor at the moment, but he wouldn't be the first black actor considered for Superman. Early in the development of Superman Returns, Will Smith was under consideration to play the Man of Steel! At the time, Will Smith was one
of the biggest stars in the world, so it's understandable why he'd be asked.
It's also understandable why he rejected the offer: after receiving backlash for playing the traditionally white hero of Wild, Wild West, Smith had zero interest in playing an even more iconic white character. He'd go on to star in his own superhero movie with Hancock and play Deadshot in Suicide Squad.
